Automated statement reconciliation connects to your ERP through an API, pulling supplier, ledger and GRN data out automatically and posting matched results, and flagged exceptions, back in. For SAP, Oracle, NetSuite, Dynamics, Sage and Infor, that's usually a standard connector, not a custom build, so most teams are live within weeks.
For the wider picture of what changes once reconciliation is automated, see our guide to supplier statement reconciliation.
Master data flows out of your ERP for matching. Reconciled results flow back in for posting. Nothing about your chart of accounts or approval workflow has to change.
"We'd love to automate reconciliation, but we don't want a six-month ERP project" is one of the most common objections finance teams raise before they've looked at how the integration actually works. For most ERPs, that fear doesn't match the reality.
What moves between the two systems
A reconciliation platform needs two kinds of data from your ERP: supplier records and GL codes to set up each account, and the purchase ledger, purchase orders and goods receipt notes to build the "your side" of every comparison. Once a statement line is matched, or an exception is resolved, the result posts back, so the reconciled position lives in the ERP ledger rather than a separate spreadsheet.
How the connection works
Most mainstream ERPs have a standard API that supports this kind of integration out of the box. One AP automation vendor's rundown of ERP connections lists real-time API sync as the default route for SAP S/4HANA, SAP Business One, Oracle Fusion, Oracle EBS, NetSuite, Microsoft Dynamics 365 and Sage. For older or more customised systems, a file-based connection, structured exports over encrypted SFTP, is a common fallback, and for anything unusual, a custom API build fills the gap.
None of these methods change what's already inside your ERP. They read and write through its existing structure.
What's different by ERP
- SAP: S/4HANA and Business One typically connect through a standard API; older ECC6 environments sometimes need a file-based bridge.
- Oracle: Oracle Fusion and Oracle EBS both support API integration, though EBS deployments vary enough that a quick technical check is worth doing first.
- NetSuite: NetSuite and NetSuite OneWorld have well-established API integrations, including multi-subsidiary setups.
- Dynamics: Dynamics 365 connects via API; older Dynamics AX, GP or Navision deployments sometimes need a tailored connection.
- Sage: Sage 50, Sage 200 and Sage Intacct all support standard integrations; Sage X3 and Sage 1000 setups vary more by implementation.
- Infor: SyteLine, M3 Cloud and SunSystems are typically integrated case by case, since Infor deployments are less standardised across customers.
What "no disruption" actually means
No disruption doesn't mean no project at all. It means the project is scoped around connecting two systems, not rebuilding one. Your chart of accounts, your approval hierarchy and your existing AP workflow stay exactly as they are. The reconciliation platform sits alongside the ERP, reading what it needs and writing back only the matched results and flagged exceptions.
How long it actually takes
With clean master data, accurate supplier records and GL codes, an API-based integration is typically a matter of weeks, not months. The work that extends a timeline is almost never the connection itself; it's cleaning up supplier master data that's drifted over the years, duplicate supplier records, missing GL codes, inconsistent naming. Sorting that out before integration starts is the single biggest lever for a fast go-live.
